Abstract (en)
[origin: CN210226030U] The utility model relates to an electronic assembly with a shell with cooling fins. A plurality of cooling fins extending in different directions are arranged on the outer surface of the shell. According to the utility model, the plurality of radiating fins are divided into two groups (2, 3), the radiating fins in one group (2, 3) are parallel to each other, but form an angle (alpha) with the radiating fins in the other group (2), and the angle is between 45 degrees and 135 degrees, preferably between 75 degrees and 115 degrees. The two fin groups (2, 3) are separated from each other by a fin-free region (4), wherein the fin-free region (4) extends along an axis of symmetry (S) of the plurality of fins and the width thereof continuously decreases along the axis of symmetry (S).
